Urgent-- could cisco uc320 work with dumb switch ? how to configure

could cisco uc320 work with dumb poe switch, with its voice vlan alway in 100, I can't change it, and my phone can not find the pbx through the switch, if it can, how can I configure it.

Hi Rex,
If the switch is unmanaged the 802.1q (tagged) ethernet frames typically pass right through the switch as if the phone was directly connected to the UC320W.  In this case both voice VLAN works and data VLAN. I would guess that if a switch has PoE that it is a managed switch though.  If it is a managed switch you will need to configure ports, vlans, and possibly CDP passthrough.

    Working with Chinese characters: How to paste and modify them as sentences; not as individual images?
    From 2004, this is so far the most detailed answer I could find: http://en.allexperts.com/q/Adobe-Illustrator-1027/FONTS-display-problem-Adobe.htm, but is this really still the most up-to date solution?
    Is it possible at all to work with Chinese characters, if I don't have the Chinese version of Illustrator? (http://www.proz.com/forum/dtp_desktop_publishing/221125-chinese_in_indesign.html)

    Thanks for your reply.
    I'm using Version 17.1.0 (64-bit) - basically CS6.
    Operating system is Windows 8.1. Installed is the simplied Chinese language package.
    I have received the text in a Word document. It contains mixed characters, something like this:
    教授资料
    学术背景:
      博士;曾于波恩大学(Rheinische Friedrich-Wilhelms-Universität Bonn)、台湾师范大学、
    I have tried to paste it in the two following ways:
    1) to create a text box and paste the text. The result is that some of the characters are not showed correctly.
    2) Paste it directly without any preparation. This result into a single "image" or group of images. I can cancel modify each character one at a time, or I can dissolve the group, but the result is the same.

  • I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device.  But I have a Conceptronic router.  Will Time Capsule work with this and how?

    I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device.  But I have a Conceptronic router.
    1. Will Time Capsule work with this and how?
    2. Can my printer USB be plugged in and then shared between the devices?
    3. Can I create a network and how?
    4.  What happend when a visitor logs onto my existing wireless router?
    I'm new to Macs (well a returning user having started with Mac Plus!!) and not very technical.  Any help / advice will be much appreciated.
    Ray

    The key to what you seem to want to do is to be able to get Apple's Time Capsule router to "join" the network that your Conceptronic router.  I believe that works with some third-party routers, but I've never seen a list of those that work in such a configuration and I have no experience with Conceptronic equipment.
    You might be better off with a Network-Attached Storage (NAS) device instead of a Time Capsule.

  • I bought Numbers because my Excel files would not work with Mavericks. How can I import a non-functioning Excel file into numbers? (As of now, the file NAME transfers but data is not.) but

    I bought Numbers because my Excel files would not work with Mavericks. How can I import a non-functioning Excel file into numbers? (As of now, the file NAME transfers but data does not.)

    HI Dave,
    I'm surprised you get no message when you attempt opening the Excel document in Numbers.
    I'm assuming Numbers 3.1, since you are running Mavericks.
    Does the Numbers file that opens show any content?
    Does it contain a table?
    How large?
    Does it contain more than one tab (indicating more than one sheet)?
    Do those other tabs contain a table?
    Have you checked those tables for data content?
    There have been cases in the past of imported documents opening with white text on a white background, giving the appearance of containing nothing. Check for this by selecting a block of cells, then applying a Fill colour or a Text colour using the Format button (paintbrush).
    I'd also suggest attempting to open the Excel files using LibreOffice, which can be downloaded from the linked website.
    Regards,
    Barry

  • New 150/65 only at 94 Download AND Won't Work with Gigabit Switch

    I just had this installed today, converting up from the 35/35, and ran into these two problems:
    1.  The 150 download is only resulting in a 94.87 Mpbs.  The installer originally said it must be my PC NIC card, but I do have a GB card, so there's does not appear to be legitimate reason for the shortfall there.  I tried to change the link speed and duplex from "auto negotation" to "1 Gbps Full Duplex," but then my computer no longer even could connect.
    2.  The second issue is that I have always run my connection through a D-Link DGS-2208 Gigabit Switch because I have multiple wired ethernet computers in my office.  The installer wanted to test the connection speed directly through my computer (see above) and ran into problems, so I never even tried to revert to my original setup with the switch until he left.  However, when I did the Gigabit switch does not even recognize any activity when I plug the source ethernet cord into the switch.  It does recognize the connection to the PC and the port is lit, but no lights from connection to the wall.
    Any thoughts on what the problems could be?  I've included the "additional details" from the Fios Speed test at the standard site (can't get any details from the high speed version):

    If your computer can't negotiate a 1Gbps connection, then that is what is limiting you to 94Mbps, which is about right for a "100Mbps" port.
    There could be several reasons for this.
    A bad NIC
    A bad port on the switch
    IMO, the most likely cause is a bad cable.  1Gbps requires all 4 pairs in the cable be connected.  If only 2 of the 4 pairs are connected correctly, you will get a 100Mbps connect, but will not be able to connect at 1Gbps.  Try replacing the cable with one known to work at 1Gbps.

  • Apple TV doesn't work with HDMI Switch

    Apple TV doesn't seem to work with my HDMI Switch. Tried every combination of cables. Tried switching all devices on and off at different times. Googled to see if anyone else has tried a switcher with Apple TV. All I know is: PlayStation 3 works just fine running through the switcher. Apple TV doesn't work at all with the switcher, only when plugged directly into the TV.
    I only have one HDMI port on my Samsung HDTV and two HDMI devices (PlayStation 3, Apple TV). All my component slots are full and I already have a component switcher that's full, too. So HDMI is the only option for me.
    Any ideas? Switcher claims to support HDCP... and it does do HD resolutions (PS3 displaying in 720p).

    I use this 5x1 switch from Monoprice and it works fine, switching 3 devices, which are then routed through my AV receiver's switch... Despite the convoluted hookup, I have not had HDCP handshake issues.
    http://www.monoprice.com/products/product.asp?cid=101&cp_id=10110&cs_id=1011002&pid=2777&seq=1&format=2&style=
    The nice thing about this switch is:
    1. It works: no discernable loss in quality, switches relatively quickly, etc.
    2. It's cheaper than many others, like Gefen, or even the Xtrememac (which is 4x1)
    3. The remote has discrete buttons for each input, which is very helpful when setting up a universal remote like my Harmony 880. I can't tell from the Xtrememac picture if it's a direct input, or if you can only cycle through the inputs...
    Good luck!

  • Does Cisco ATA work with a text phone?

    I'm trying to get my Cisco ATA to work with a fax and a text phone at one of our sites. Has anyone used a text phone on an ATA?

    Hi Stephan,
    Yes I posted in the wrong forum by mistake.
    I've now managed to get it working so a text phone does work with an ATA.
    A textphone is used by the deaf or hard of hearing. It has a keyboard and LCD screen and allows the user to type text which is relayed through to a textphone at the other end.
    Thanks

  • Urgent--custom servlet not working with https/gateway of the portal server

    We have created the custom servlet to add some more authentication to the login screen. I have explained detaildely below.
    We have set if password reset change password screen should come by using identity server.
    First screen comes which asks �user id� and �password�.
    after this next screen comes with �old password�, �New Password� and �Confirm Password� (as we have forcefully asked user to change password after reset by using identity server ).
    On this page we have added two new filed �Date of Birth� and �Date of Joining�.
    And we are forcefully transferring request to our Custom Servlet which will validate the �Date of Birth� and �Date of Joining� from the database and submit the same a form as required by Login Servlet to validate the default parameters �old Password�, �New Password� and �Confirm Password� (which is the default validation without adding custom Servlet).
    This whole process is working with �http� protocol and giving �unable to connect� host with �https� protocol.
    Without custom Servlet process is like this, which is working
    Login (usrid, password) � Login (Old Password, New Password, Confirm Password) � Portal home Page
    With custom Servlet , Which is not working with �https� Protocol. we are getting the message "Authentication Failed" screen.
    Login (usrid, password) --> Login (Old Password, New Password, Confirm Password , Date of Birth, Date of Joinig) --> Custom Servlet validate Date of Birth, Date of Joining --> Login (Old password, new Password, Confirm Password) --> Protal Home Page
    This one works with http, whereas this one gives the "Authentication Failed" screen with the https.
    Please let me know if anybody have implemented this and help me to resolve the issue.

  • Cisco ESW500 conflict with netgear switches?

    We until recently had two x Netgear Managed Switches. One kept locking up intermitently, so we decided to replace it and bought the Cisco ESW500.
    The two managed switches can link together ok, but we have another issue now.
    Some of our users connect to the switches via Netgear FS108 Desktop Switches and other connect in direct. The direct users can connect to the Cisco fine, any 'hubbed' users cannot connect into the cisco and instead have to connect to the Netgear.
    If only one user connected via a 'hub' it is ok ... but not multiple users.
    Not a huge issue at this stage, but once we run out of space in the netgear it will be.
    Any ideas?

    Yes, there is a bit of additional flexibility in how you configure the ports and what is allowed.   By default all ports are 'access' ports and the uplink ports are set for inter-switch connections ... AKA - 'Switch'.  Using the smart ports application is the best way to change this!  
    Kindest regards,
